To all whom it may concerit:

Be it known that LWILHELM VAJNA, profes sor,a subject of the Emperor ofAustria-Hungary, and a resident of Buda-Pesth, Austria- Hungary, haveinvented certain new and useful Improvements in Nerve Bro'aches, ofwhich the following is a specification.

The present invention relates to improvements in nerve-broaches fordentists"use; and the object of the invention is to provide aninstrument of the class described having a loop in the stemthereof,wherebythe broach is rendered more flexible, breakage of theportion within the mouth is prevented, and the loop will serve as anindicator or guide as to the position of the point.

The invention is illustrated in the acc0m= panying drawings, in whichFigure 1 is a side elevation. Fig. 2 is a view at right angles to Fig.1; and Fig. 3 is a View similar to Fig. 1, the size generally used.

By referring to the drawings it will be ob served that the broach isprovided interme diate of its point I) and handle o with a coil .or loopa, made by turning or coiling the metal one or more times upon itself.By rea= son of this loop greater flexibility is given to the broach.From the position of the loop the position of the point will be known,and in case of breakage the break is more likely to oceur at the loop,whereby this danger of the breaking of the portion Within a personsmouth is lessened.

Having thus described my invention, what I claim isg A nerve-breachhaving a loop in the body portion thereof, substantially as described.

Signed by me at Buda-Pesth, Austria-Hungary, this 11th day of July,1898. I x
